Problem porting from DevC++ to C:B

[xtracto]

Well, I have a DevC++ project.
 It is quite complex, so far I am using:
- OpenGL
- SDL
- wxWidgets
- mingW

I am trying to test the C:B project to see if I migrate form DevC++. So I open the program and import the DevC++ project [Project/Import/DevC++ Project]

Everything went so-so, Somehow the Output Filename managed to get wrong (something like "H:\my document\H:\my documents". Anyway, that was easy to fix.

Then I made sure the MingW installation with al the needed libraries (for the tools mentioned before) was beeing used, everything ok.


Then I try to rebuild all [Build/Rebuild All] and all the files compile so far, but I got some nasty errors:

Mainly, some wxWidgets functions dont want to be digested using C:B configuration... from my previous experience with DevC++ I *think* this may be fixed modyfing the order of the libraries being lined, but I have tried without a good result.

Of course I think I do not have to mention the project was compiling OK on DevC++. Yes, I am using the same mingW path to compile via Code:Blocks, I *thought* it was going to be more straight forward.

Any help?

Thank you!

btw, I think the CTRL+C shortcut is not working in the C:B build log window

It appears you're linking the same library twice... perhaps in your GLOBAL options you got the wxwidgets library....

but the "different size" makes me think you're trying to link to another different wxwidgets library... maybe you got your lib paths wrong...

I have a hunch... do you have defined in your project, WXUSINGDLL  (for compiler)? It seems to try to link to wxwidgets statically...

Other than that, I couldn't tell. Try enabling the "full commandline" on your compiler options so we can help you troubleshoot.

Hello, I have tried without luck.

It appears you're linking the same library twice... perhaps in your GLOBAL options you got the wxwidgets library....

but the "different size" makes me think you're trying to link to another different wxwidgets library... maybe you got your lib paths wrong...

Ok, I made a fresh install of C:B (using RC2 installed, previously I had downloaded the CVS build version) so it is now installed with the default options. I checked the global linker options and there are no libraries listed [Settings/Compiler/Linker]

All directories ARE pointing to the mingW installation of the NEW C:B
[C:\Program Files\CodeBlocks\Include]
[C:\Program Files\CodeBlocks\lib]

I have a hunch... do you have defined in your project, WXUSINGDLL  (for compiler)? It seems to try to link to wxwidgets statically...

I defined WXUSINGDLL, didnt needed to use it on DevC++, so I do not know what is its use exactly. I guess it makes my program use wx libs dinamically instead of statically (I prefer the statically linked libraries).

Other than that, I couldn't tell. Try enabling the "full commandline" on your compiler options so we can help you troubleshoot.

I do not understand this last one, is that "full commandile" an option on the C:B IDE?.
 Anyway, I have tried to se what is the instruction C:B  gives to mingW but none of the windows give me that information.
This is what I got from the "Build Log" after with a Rebuild command:

It is curious that I get "0 errors, 0 warning" huh...

Any hints?
thank you again!

The "Full Commandline" is in Compiler Setting, Other. There's something that says "Compiler Logging:". Normally it says "Task description". Change it to "Full Commandline".

Well, so far I haven't been able to fix the problem. Anyway it seems it is a compatibility problem with wxWidgets.

I disabled all the wxWidgets code in my app and it compiled .

I guess I'll have to use C:B for non-wx code. Anyway it will help me to test how the C:B IDE.

Cheers.

[rickg22]

Hmmm.... it seems that the compiled files  try to link the library statically. Check if you have WXUSINGDLL In your project's build options, under the "#defines" tab.

Then rebuild.
